MicroSD cards can only hold up to 2GB. MicroSDHC (HC means "High Capacity" ) range from 4GB to 16GB currently, with the possibility of 32GB. A microSDHC card uses a different protocol to transfer the data, so a device built for microSD cards may or may not read it; it depends on the device. The hardware controller is different, but some newer devices can be updated to newer firmware to read them. Again, it all depends on the device.
Wikipedia has a page on SD cards in general that has a section on the SDHC types: http://en.wikipedia.org/wiki/MicroSDHC#SDHC
